The situation varies depending on the cause. If it is acute laryngitis caused by an injury, it is not contagious. However, if it is caused by an infection, such as by the epidemic influenza virus, or by Bordetella pertussis causing acute laryngitis, these infectious diseases cause inflammation of the larynx and are contagious. Or in cases of general bacterial and viral infections, there can be cross-infection, but they are not contagious.

What causes acute laryngitis in children?

Pediatric acute laryngitis is generally considered to be an infection, with viral infections being most common, accounting for about 80% of cases. This includes respiratory syncytial virus, influenza virus, parainfluenza virus, and Coxsackievirus, all of which can cause acute laryngitis. Of course, there are also cases caused by bacterial infections, with gram-positive bacteria being more common. Additionally, special circumstances such as procedures, gastroscopy, bronchoscopy, etc., can cause laryngeal injuries, or the ingestion of irritant food items might also damage the laryngeal tissues, subsequently leading to symptoms of laryngitis.

Does acute laryngitis in children recur?

Acute laryngitis in children can recur, similar to tonsillitis. Some children may have inherently lower immune function in the larynx, or a relative defect, which makes them prone to inflammation in the larynx whenever there is an upper respiratory infection. Therefore, we generally inform parents that if the child has a history of laryngitis, they should be aware of this condition in the future, especially of sudden respiratory difficulty at night and hoarseness. It is important to pay attention as laryngitis tends to worsen at night, and if it occurs, we recommend seeking medical attention promptly.

Is acute laryngitis in children contagious?

Is acute laryngitis in children contagious? It depends on the pathogen causing the infection. If the infecting pathogen is contagious, then certainly it can be transmitted. If the infecting pathogen is not infectious, then of course it will not be contagious. Contagious examples include diphtheria, influenza virus, and Coxsackie virus, which can cause transmission, so it is important to isolate as much as possible. If it is a bacterial infection, it is generally not contagious. Therefore, one cannot simply say whether acute laryngitis in children is contagious or not; it depends on what the infection source is for this particular case to determine whether it is contagious or not.

Does acute laryngitis in children cause fever?

Generally speaking, acute laryngitis in children is accompanied by fever, as it is caused by viral or bacterial infection. Inflammatory response: redness, swelling, heat, and pain. Local reaction: In children, local infections can easily lead to systemic symptoms, especially fever, which can vary in intensity but generally remains relatively easy to reduce. It is unlikely to be extremely high fever. If the body temperature exceeds 38 degrees Celsius, or if the child shows poor spirits during fever, oral antipyretics or rectal fever suppositories can be used to alleviate the symptoms of fever.

Do children with acute laryngitis have a fever?

Acute laryngitis may occur with or without fever. For children, acute laryngitis is primarily a local symptom, but because children generally do not have robust immune function, local infections can easily lead to systemic symptoms. Among systemic symptoms, acute laryngitis frequently manifests as fever, typically presenting as either mild or high fever. It is relatively rare to see extremely high fever. Therefore, it is usually recommended that if the fever exceeds 38 degrees Celsius, or if the child appears lethargic during the fever, oral administration or rectal insertion of ibuprofen suppositories or acetaminophen suppositories can be effective treatments.
